Q: Can you explain the difference between “Enable RFQ functionality per product” and “Enable RFQ functionality per store”?
A: The shopowner can decide to enable the quotation functionality on a product per product basis. So in the same category (product list) there can be a product that is quotable and one or more that are not.
The shopowner can also enable or disable quotations for a complete website, store or storeview. Basically it means Cart2Quote does support the store settings of Magento.
